These are timers for playing Aliens, or other science fiction games where a timer may come in handy.
The theme is meant to evoke the feeling that you are on a starship somewhere in deepspace, with the ship's artificial intelligence known as Mother alerting you with warnings of impending biological threats before your time runs out.
To add a bit more of the aliens element to the timer, one set has motion trackers chirping away in the background while to the timer runs out.
They only took about 4 hours to make. The rest of the story, and the timers themselves can be found here.
